Winder syncs to public NTP atomic time servers and shows you time you can trust, accurate to the millisecond. Open the app, read the time, set your watch. That's it. Built for collectors who care about the seconds. WHAT YOU GET Atomic time synchronization via NTP (NIST, PTB). The drift strip at the top of the screen shows your device's exact offset from atomic time. No guessing, no rounding. A continuous-sweep second hand that glides like a Spring Drive. Analog face, digital display, or both. Dauphine hands with a center ridge that catches light. Four bundled typefaces. Optional countdown sound cues (mechanical or electronic) so you can set your crown without watching the screen. 12 dial themes drawn from real watch materials: meteorite with Widmanstätten crystal lines, aventurine glass with 1,375 shimmering inclusions, sunburst rays with a rotating specular beam, tapisserie grids, black ceramic waves, and more. Every surface animates. Light sweeps slowly across crystal boundaries. Inclusions catch and release a migrating glow. Specular beams rotate over hours. These are not wallpapers. They are living dial surfaces. Three themes are free. Winder Pro unlocks the full collection with a single purchase. No subscription. PRIVACY Winder collects no data. No accounts. No analytics. No tracking. No crash reporting. Your preferences stay on your device. The only network request is the NTP time sync. That's the entire privacy policy. BUILT BY A WATCH COLLECTOR I couldn't find a precision clock on the phone that felt worthy of the watches it was meant to serve, so I built one. Every dial, every animation, every pixel is crafted with the same care you'd expect from the watches Winder serves. Made in Mexico. Part of the Watchdex ecosystem. watchdex.app
NTP Candle Timer
Read full descriptionHide full description
A clear candle countdown beside your charts. NTP Candle Timer is a timing utility for stock, futures, forex and crypto traders. Watch the time remaining in a repeating interval without covering your trading platform. NETWORK-TIME SYNC The app periodically compares device time with network time and applies the measured offset to its display. The final 15 seconds show hundredths of a second. Actual accuracy can vary with the network, device and your trading platform's time source. The app does not change your device clock. YOUR INTERVAL, YOUR DISPLAY Choose 1, 3, 5, 15, 30 or 60 minutes. Use landscape or portrait orientation, select a font and color, and optionally show the battery indicator. AN OPTIONAL REFERENCE CLOCK Display Local, New York or UTC time below the countdown. New York follows daylight saving time automatically. This option is off by default and does not change the countdown or the timezone of your market alerts. VISUAL AND SOUND ALERTS Choose warning colors, final-seconds sounds and a session-end sound. Set market open and close reminders in your device's local time. Keep the app open during your session; it is not a background alarm service. The core timer and reference clock are free with banner advertising. An optional auto-renewable subscription removes banner ads and unlocks Pulse and Afterglow visual effects. The app interface supports English, Korean, Japanese, Spanish, Portuguese, German and French, following your device language preferences. Other languages fall back to English. NTP Candle Timer does not provide prices, trading signals, brokerage services or financial advice. Verify critical timing with your trading platform. Payment is charged to your Apple Account at purchase confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel subscriptions in your Apple Account settings.

Verdict
The clearest difference is ads: Winder at none against NTP Candle Timer's shown. NTP Candle Timer's advantage is iOS requirement (15.0 vs 26.2). On price, update cadence, in-app purchases and device support there is nothing between them.
